''Discworld Noir'' is the third ''Literature/{{Discworld}}'' AdventureGame. It was made by GT Interactive and released in 1999.

The game follows Lewton, the Disc's first and only PrivateInvestigator. The game starts as Lewton is given a simple case to find a man. Since this is an AdventureGame set on the Discworld and acted out through a FilmNoir genre filter, it soon becomes clear that there is far more going on.

While the game in many places is an AffectionateParody of FilmNoir, it also plays many of the tropes straight, even if they are given a unique Discworld spin.
----
!!'''Tropes''':
* BadassLongcoat: Lewton. Brown trenchcoat with leather added over the shoulders, and a [[NiceHat matching fedora]].
* BeamMeUpScotty: Played with as a ShoutOut to ''{{Casablanca}}'':
---> '''Lewton:''' Play it again, Sam.
---> '''Samael:''' You know what? No one's ever going to believe you said that.
* BizarreAlienSenses: Gaspode teaches Lewton how to use [[spoiler: werewolf "nasal vision"]].
* ConnectTheDeaths: Played straight.
* ConspiracyTheorist: Malaclypse, a servitor of Errata, Goddess of Confusion and Misunderstanding. This is a ShoutOut to out world Malaclypse the Younger (a penname for Gregory Hill), the supposed creator of ''Principia Discordia'', which details the worship of Eris, the Goddess of Chaos.
** [[spoiler:A reasonable chunk of his gibberish [[CassandraTruth is actually true]], and covers a lot of Discworld (and Discordian) mythology/history.]]
* ContinuityNod: Lewton mentions that the Elucidated Brethren of the Ebon Night (from ''Discworld/GuardsGuards'') has been "forcibly disbanded."
** One stained-glass window at the Temple of Small Gods represents an angel presenting a pizza (with a small bay leaf) to a prophet, a reference to a religion mentioned in ''Discworld/{{Mort}}'' that believed that the Discworld was created in the image of a pizza.
* CursedWithAwesome: Discussed. Lewton isn't very happy about [[spoiler: becoming a werewolf]], but [[spoiler: Carlotta (who infected him)]] says it's a great gift. It does turn out to be pretty useful.
* DarkerAndEdgier: The entire game feels like a dark Watch book, to fit with the Noir theme. It is also quite darker than the two previous Discworld games, both in feel and in colour palette. Actually works.
* DeadpanSnarker: Lewton, and oh-so-many others.
** WorldOfSnark: [[UpToEleven possibly even more than the books]].
* [[spoiler: TheDogWasTheMastermind]]: Well more accurately the bestial serial killer is [[spoiler: the god Anu Anu who spends most of his time in the form of a small dog. However it is his worshippers who choose his victims and they are all in turn being manipulated by the real mastermind]].
* EditorialSynaesthesia: [[spoiler:Werewolf vision]]
* EldritchAbomination: [[spoiler: Nylonathotep]]
* EvilSoundsDeep: Horst. Really bizarrely, [[HeyItsThatVoice when you realize]] he's one of several characters voiced by Robert [[Series/RedDwarf "Kryten"]] Llwellyn.
* {{Expy}}: Many of the characters in the game are quite clearly Discworld versions of characters from ''{{Casablanca}}'' and ''Film/TheMalteseFalcon''. "Tomb evacuator" Laredo Cronk is an obvious [[Franchise/TombRaider Lara Croft]] reference, and the IndianaJones theme occasionally ''almost'' plays in the background of the archaeologist's guild.
* FantasticNoir
* FemmeFatale: [[spoiler: Carlotta]].
* FilmNoir: a bitter, cynical, life-weary, alcoholic detective narrates his crime investigation in [[WretchedHive a dark, corrupt city]]. Almost no one is telling the truth or can be trusted, and adultery, blackmail, murder and conspiracy are the least despicable things perpetrated. And it's always night and it's always raining.
* {{Foreshadowing}}: If you examine the fountain in the Temple of Small Gods, Lewton says that until someone is found murdered in the fountain, it is of no interest to him. [[spoiler:While not a murder victim, Mooncalf's corpse ends up floating in the fountain after his death by SmiteMeOhMightySmiter.]]
* FriendOnTheForce: Playing the role of [[Film/TheMalteseFalcon Detective Tom Polhaus]] is Corporal Nobby Nobbs. So no help there.
* FriendlyNeighborhoodVampire: The vampire pianist Samael, probably a black ribboner.
* GenreSavvy : Some of the villains, [[TheoryOfNarrativeCausality not that it surprises anyone.]]
* GenreShift: [[spoiler: For the most of the game the game seems like an AffectionateParody of FilmNoir in general, and ''Film/{{Casablanca}}'' in particular. Then towards the end, it suddenly turns out to be a CosmicHorrorStory, with Noir elements.]]
* GodsNeedPrayerBadly: As usual on the Disc. [[spoiler: The entire plan turns out to be an attempt by the worshippers of the small god Anu-Anu to have their god defeat Nylonathotep and thus win enough believers to become a recognised deity.]]
* HalfHumanHybrid: The bartender Mankin is half-elf, in the Discworld setting, that makes him very unpopular (since [[OurElvesAreBetter Elves]] are cruel and vain beings from a parallel dimension), and gives him no special powers. He is a very bitter person.
* HardboiledDetective: Lewton both embodies and parodies this trope, due to the Disc's TheoryOfNarrativeCausality; he doesn't know ''why'' being a private investigator means he has to wear a trenchcoat and fedora, but he's quite sure it does.
--> '''Lewton:''' A lot of strange things had happened to me since becoming a private investigator, but the weirdest was the irrepressible sensation that the most important thing for me to own as a P.I. was a door, with my name painted on the glass. Some mysteries are best left unsolved, I guess.
* HeyItsThatVoice: Robert Llwellyn, of Series/RedDwarf and ScrapheapChallenge fame, voices Horst, Leonard and a Palace Guard among others, while Nigel Planer from ''TheMagicRoundabout'' does most of the others. Lewton and Nobby are [[ManOfAThousandVoices (apparently)]] Rob Brydon.
** Never mind ''TheMagicRoundabout''; Planer definitely plays Worb as an ActorAllusion to Neil from ''TheYoungOnes''.
** You can hear Rob Brydon doing the same voice [[http://www.youtube.com/watch?v=yNJStquFEGk&feature=related while mock-offended on QI]].
* HostageForMacGuffin: Played straight, [[spoiler: Horst holds Ilsa for the Golden Sword]].
* HowWeGotHere: The game opens with a cinematic in which the protagonist is chased down and stabbed to death. [[spoiler: You spend the first half of the game looking for the McGuffin whose possession will result in your untimely demise.]]
* IKnowYouKnowIKnow: Lewton tries to do this on Malaclypse - it works, after a fashion.
* InMediasRes: The game opens with Lewton ''buried'', having been fatally stabbed in a cinematic. The first half of the game is his story of how he got into this situation, the second is how he deals with its aftermath.
* LargeHam: In-game actor Privetier is a huge ham, much to Lewton's displeasure.
* LetsPlay: A video playthrough by [=TheRussianGestapo=] [[http://www.youtube.com/watch?v=HuY8hEw5724&hd=1 on YouTube]].
* NoirEpisode
* OnlySmartPeopleMayPass: It looks like the game is headed for this when an ancient guardian wants to ask you a riddle to see if you are worthy to receive the McGuffin. Then come the subversions, first by the guardian who happened to forget the riddle during his 400-year-wait (but still insists to only hand the item to those who answer it) and then by Lewton who points out that someone of the ''un''worthy faction would just hack the weaponless guardian to pieces. As he's in somewhat of a hurry, he gives the guardian the option to hand over the McGuffin - or he'll just ''pretend'' to be unworthy enough...
** The guardian relents.
* OutOfCharacter: Insofar as characters who appear in the books are hanging about, they're reasonably true to the books-except for Vimes. Vimes holds a massive grudge against Lewton because the particular indiscretion for which Lewton was fired [[spoiler: (accepting a bribe)]] ranks just short of murder in Vimes' book (which is true to the books), and he's only too willing to accept that being found unconscious at the crime scene is proof of guilt. This in contrast with his portrayal in the books where he hates "clues" (like, say, being found unconscious at the crime scene) because they often create fantastic stories out of the theories but do little to solve the case. In the books his first duty is to justice, and if that means letting the guy he doesn't like walk so that the real culprit ends up behind bars, he doesn't want it any other way.
** Essentially, Vimes has been handed the role of Sam Spade's nemesis Lt. Dundy even though it's not a great fit, because it's still much closer than giving it to, say, Carrot.
** Could be Fridge Brilliance at work: Vimes may actually know that Lewton isn't a likely suspect, but wants Lewton to clean up this mess to make amends for his past failure as a copper. Leaning on Lewton may be Vimes playing out the same hard-ass role he adopted in ''Night Watch'' for his "ginger beer trick".
* ParodyName: Mundy for Thursby; Jasper Horst for Casper Gutman; "Mount" Malachite for "Moose" Malloy; [[spoiler: Nylonathotep the Laddering Horror for [[CthulhuMythos Nyarlathotep the Crawling Chaos]].]]
* PosthumousNarration: Lewton gets killed in the opening cinematic, and and a good chunk of the game is a flashback.
--> '''Lewton:''' I've had some bad days since I started work as a private investigator. But I've never woken up ''dead'' before.
* PrivateEyeMonologue: Played straight and parodied, with the usual Discworld insistence that metaphors have to be precise. Also, Lewton is a very, very bitter man.
* RedHerring: Unusually for an [[LawOfConservationOfDetail adventure game]], there are a few false leads, such as [[spoiler: the story of the madman Azile, who buried people upside-down, and Malaclypse's gibberish. Mostly.]]
* ShoutOut: The game has innumerable shoutouts to {{Casablanca}}, and popular culture in general. There are also two framed pictures showing landscapes from the previous, more colorful, Discworld games.
** The McGuffin of the first half of the game is a falchion. A [[Film/TheMalteseFalcon Tsortese]] [[IncrediblyLamePun Falchion]]. [[spoiler: That is also the Discworld's equivalent to the AppleOfDiscord, or would if the writing on it hadn't been "Batteries not included"]]
* SmiteMeOhMightySmiter: The death of [[spoiler: Mooncalf. He goes mad with guilt over the actions of his cult and renounces all gods while standing on top of the Temple of Small Gods in a thunderstorm... it was inevitable, really.]]
* TakeThat: The Lara Croft Expy basically serves as a vehicle for the writers to tear into the Franchise/Tomb Raider franchise.
** Ten years laters, with all the Franchise/TombRaider re-releases, and sequels and stuff, it's become HilariousInHindsight.
* ThemeSerialKiller: There was a parody of ''Film/TheatreOfBlood'', with the plays of [[Discworld/WyrdSisters Hwel]], the Disc's version of Shakespeare.
* TrojanHorse: Used by Lewton to board the ''Milka'', and by a killer to enter the Patrician's Palace.
* WhamEpisode: More like wham scene - [[spoiler: the library scene when you finally figure out that the game is a CosmicHorrorStory]].
** And later still, when Lewton finally pieces some things together:
--> '''Lewton:''' At that moment I realized what was odd about the bone. [[spoiler: It had been a human femur.]]
* WholePlotReference: To ''Film/TheMalteseFalcon'', ''Film/FarewellMyLovely'' and ''Film/TheBigSleep''. All happening at the same time, and with one character playing the roles of all three {{Femme Fatale}}s.
